Leptocottus armatus (Cabezon; Pacific staghorn sculpin; Staghorn sculpin)

Language: Mandarin Chinese; Polish; Salish; Spanish

Wikipedia Abstract

The Pacific staghorn sculpin, Leptocottus armatus, is a common sculpin (Cottidae) found in shallow coastal waters along the Pacific coast from Alaska to Baja California. The sole member of its genus, it is unusual for having spined antler-like projections on its gill covers; it can raise the projections as a defense mechanism.Staghorn sculpins are slender fish, with a grayish olive above, pale creamy yellow sides, and a white belly.
